Virtual Try-On

  • Can I try on glasses before I buy?

    With our 3D Virtual Try-On tool, you can upload a video of yourself to get a realistic 180-degree view of how a frame will look and fit on your face. Uploading a video is easy—the hard part is deciding which frame to buy when you can try on up to 50 frames!

    Click here to get started.

    We also offer a 2D try-on feature called Zenni Frame Fit™, for those who just want to upload a picture and get a basic idea of how a frame will look. Click here to use Zenni Frame Fit™.

  • How do I create a 3D Virtual Try-On video? Is it required?

    We encourage you to create your own video for the 3D try-on, but it’s not required. However, using a 3D Virtual Try-On of yourself will be a much better guide to how the glasses will look and fit on your face than using a photo of a model. After clicking “CREATE A TRY-ON,” you may need to allow your device access to the camera. Tips on creating the video:

    - A light or plain background is best, such as a white wall behind you.

    - Record a video of yourself turning your head side-to-side as instructed. While doing this, you will want to make sure that your head is straight on and level, with your pupils clearly visible.

    - Use a standard card (such as a credit card), and place it against your forehead as instructed in order to make sure the glasses are scaled to the right size (you may skip this step, but we encourage you to do it for best fit).

    Voila, your 3D Virtual Try-On is complete! To see yourself in glasses, click “TRY ON” on a product detail page, choose the image of yourself, and then move your mouse (or swipe for mobile) left and right on the Try-On image to see yourself from different angles in the frame. To compare yourself wearing different pairs, click "TRY ON" on a product listing page, or in your Favorites, for a static front view to see what looks best.

  • Can I redo my DITTO 3D Virtual Try-On?

    Yes! If you don’t like the results of a video you took, you may redo it. Go to your Account Overview, click "My TryOn" and then "CREATE NEW VIRTUAL TRY ON."

  • Are my try-on images and videos private?

    Yes. We will not use or distribute any images or videos that you upload to our Virtual Try-On or Frame Fit tools.


  • What frame style is best for my face shape?

    Our Face Shape Guide features tools to help you discover what your face shape is, as well as links to flattering frames by face shape for men and women.

  • What frame material is right for me?

    It depends on what features you are looking for. The following categories can help with your decision:

    Weight: If you want a super light frame, go with one that's 15 grams or lower. Titanium frames are generally very light.

    Material: You have the choice between metal or plastic. Metal tends to be lighter. Plastic frames tend to be more durable.

    Flexibility: This is a nice feature to have for kids or sports glasses. We have a line of kids plastic flexible frames that are forgiving and durable.

    Color: Plastic frames tend to come in more color options, especially acetate plastic.

    Hypoallergenic: Stainless steel, titanium, and acetate frames are hypoallergenic.

  • Do the frames come in different sizes?

    Most of our frames come in one size, but not all. The details will be listed under the product description. Please use the size filter to find the one that best suits you.

  • Do you offer low bridge fit/Asian fit frames?

    Yes, we offer a great selection of universal bridge fit also known as low bridge fit or Asian fit frames. Check out our selection by clicking here.

  • What do the numbers printed on my frame mean?

    Non-Zenni frames: Some frames have a series of numbers printed on the inside of a temple arm (the part that goes behind your ear). The first numbers are typically the manufacturer’s style number and a color code. But farther down the temple arm, there may be important numbers that refer to the dimensions of the frame. These numbers are the measurement, in millimeters, of the lens width, nose bridge width, and temple arm length. Often the lens width and nose bridge width are 2-digit numbers separated by a square, and a temple arm length is a 3-digit number in front of or behind the others. Knowing these numbers can help you choose a frame similar in size when shopping.

    Zenni Frames: You will find a frame number that consists of 6 or more numbers which will help you locate the frame on the Zenni website.

    FAQs: Your Guide To Prescription EyeGlasses | Zenni Optical (1)

  • Full-rim, half-rim, or rimless?

    Your Rx may be too strong for half-rim or rimless glasses, so full-rim would be your option. Full-rim glasses, especially in the nerd-chic look, are very popular. They are generally more durable than half-rim or rimless frames. Half-rim frames are great for people with slim faces. They show more of your face than full-rim frames, and are more durable than rimless glasses. Rimless glasses are great for people who will treat their glasses delicately, and who want their glasses to be practically invisible on their face.

  • Can I get the frames in a different color?

    Most of our frames come in multiple colorways. If a frame comes in more than one color, you will see the options on the frame’s product description page.

  • My frame is out of stock. Can you notify me when it's back in stock?

    Yes. When a frame is out of stock, you will see an "out of stock" message below the frame. Enter your email address in the space provided, and we'll let you know when the item becomes available.

  • What frames can have custom engraving?

    Our custom engraving feature can be added to many of our acetate and plastic frames as long as the temple arms are wide enough. The easiest way to find eligible frames is to use the filter tool and select “Custom Engraving” under Feature.

    It depends on the frame whether text or icons can be engraved, as well as placement options (inside the temple arm or outside).

    To see what content is allowed, please see our custom engraving guidelines here.

  • What can I do if my frames don't fit perfectly?

    New glasses often need minor tweaks to fit your face right. It’s best to have an optician fine-tune the glasses for you, but you can also make adjustments yourself with our How to Adjust Your Glasses guide.

  • How can I tell if the frame and lenses qualify for Z87.1 standards?

    Z87.1 glasses will be designated with a “Z87-2+” or “Z87+” marking on the frame. Your prescription lenses willalso be etched with “Zenni+” to designate the safety rating as required by ANSI.

  • Sport Protective Eyewear

  • What are ASTM standards?

    ASTM International, is an international standards organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services. ASTM F803 refers to protective eyewear standards for various sports. F803 is the strictest standard for protective eyewear. For glasses to meet the ASTM F803 standard, they need to pass a high velocity impact resistance test, including clarity and strength of the lenses.

  • Why is it important to wear eye protection during sports?

    Recreation and sports activity are responsible for thousands of eye injuries every year. Approximately 90% of all eye injuries can be easily avoided if wearing appropriate eye protection, like those with ASTM F803 designation.

  • How can I tell if a frame and lenses meet the ASTM standards?

    All of our ASTM tested goggles are tagged as “Sport Protective”. The compliance standards, as well as the sports for which the product has been tested for, will be outlined on the product description page and the accompanying insert card shipped with the goggles.

    Only the approved impact-resistant Polycarbonate and Trivex® lenses are offered for this line of products.

Prescriptions (Rx)

  • How do I read my prescription?

    If you need glasses, your eye doctor will provide you with a prescription for corrective lenses. Eyeglass prescriptions may be written in different ways, though most are either printed or handwritten in horizontal rows. The first row is the prescription for the right eye (OD), and the second row is for the left eye (OS). Within each of these rows are three values: Sphere (SPH), Cylinder (CYL), and Axis. The SPH number corrects for nearsighted [indicated with a minus (-)] or farsighted [indicated with a plus (+)] vision. The CYL number and AXIS number correct for astigmatism. You may also have another field labeled as ADD which corrects for the reading power used in a bifocal or progressive lens. To learn more about how to read your prescription, click here. Lastly, eyeglass prescriptions sometimes include the pupillary distance (PD) measurement, which is the distance between your pupils. PD is needed to determine where the optical center of the lens will be for clear, accurate vision. If your prescription does not include your PD, you can measure it yourself with our guide here. An eyeglass prescription will usually expire in 1-2 years, depending on which state you received your eye exam.

  • Can I get a list of optical abbreviations?

    Here is a list of some optical abbreviations that will help you order your glasses from Zenni Optical:

    ADD (also NV-ADD): the Near Vision (NV) Reading ADDition correction on a multifocal Rx. Can be used for bifocal or progressive glasses, or for single-vision reading or computer (intermediate) vision glasses.

    FAQs: Your Guide To Prescription EyeGlasses | Zenni Optical (2)

    AR: Anti-Reflective. A coating that reduces reflection on the lenses.

    AXIS: the angle at which the Cylinder (CYL) is placed on a lens to correct an astigmatism. It ranges from 1 to 180.

    BAL: the Rx calls for balance lenses, meaning the same Rx for each eye. Often used when a person has no sight in one eye, so both lenses will have the same thickness.

    BD, BI, BO, BU: a prism correction on your Rx (may be indicated with Δ, and one of these four abbreviations. The B stands for base, and it could be base down (BD), base in (BI), base out (BO), or base up (BU).

    CYL: the Cylinder. Combined with the AXIS, the CYL corrects an astigmatism.

    DS: the abbreviation for diopter simplex. An eye dr. may write DS on an Rx in the Cylinder (CYL) field if no astigmatism correction is needed.

    DV: distance vision.

    FT: flat-top bifocal.

    NV: near vision.

    NV-ADD (also ADD): the Near Vision (NV) Reading ADDition correction on a multifocal Rx. Can be used for bifocal or progressive glasses, or for single-vision reading or computer (intermediate) vision glasses.

    OD: Latin for Oculus Dexter, meaning the right eye.

    OS: Latin for Oculus Sinister, meaning the left eye.

    OU: Latin for Oculus Uterque, meaning each eye.

    PAL: Progressive Addition (or Adjustment) Lens: sometimes on a Progressive Rx an eye dr. will write two different numbers for the NV-ADD, perhaps +2.25 and +2.50, to increase the reading power in the NV-ADD for Progressive lenses.

    PD (Pupillary Distance): the PD is the measurement of the distance between your pupils. This is needed for the manufacturer of the eyeglasses to know where to place the optical center on each lens, so you can see well with the glasses.

    PL: Plano. Latin for "flat." If this is in the SPH section of an Rx, it means no nearsighted or farsighted correction is needed.

    RX: a prescription.

    SPH: the first section on an Rx. It corrects nearsighted or farsighted vision.

    UV: the abbreviation of ultraviolet. UV light is invisible to the human eye, but it is UV light that gives us a sunburn, and too much exposure to it can damage the eye. All of the lenses Zenni Optical offers come with 100 percent UV protection, for free.

    VA: Visual acuity: how well the eye can see. Sometimes this may be written on an Rx, with a number such as 20/20. This would indicate that with eyeglasses made to this Rx, the vision would be corrected to 20/20 vision.

  • What is my pupillary distance (PD) and how do I get it?

    Your pupillary distance (PD) is the measurement of the distance between your pupils. Click here to learn more.

  • Can you fill strong prescriptions?

    You bet we can!

    Single-vision Rx:

    Up to -20.00 or +12.00 on the Sphere (SPH

    Up to + or - 6.00 on the Cylinder (CYL).

    Bifocal Rx:

    Up to -9.00 or +6.00 on the SPH.

    Up to + or - 6.00 on the CYL.

    Up to +3.50 on the NV-ADD.

    Progressive Rx:

    Up to -10.00 or +8.00 on the SPH.

    Up to + or - 6.00 on the CYL.

    Up to +3.50 on the NV-ADD.

    Prism (single-vision only):

    Up to 5.00 in any base direction.

  • What if I have an astigmatism?

    Most people have an astigmatism. If you have an astigmatism on your Rx, we can make glasses that will correct it.

  • Do you offer bifocal or progressive lenses?

    Yes! We offer both. If you have ADD or NV-ADD on your Rx, you can get lined bifocals or unlined progressive glasses.

  • What is the difference between the premium progressives and standard progressives?

    Our high-definition premium progressives feature wider viewing areas for the intermediate and reading areas of the lens than standard progressives. Peripheral (side) distortion is reduced by up to 40% compared to the standard design. With premium progressives, the transition from distance viewing to looking at a computer, for example, to reading up close is more seamless, making adaptation easier and more comfortable.

  • Who benefits from premium progressives?

    Anyone looking for an everyday pair of progressives with enhanced vision and minimal distortion. If you already have a pair of Zenni’s standard progressives, you’ll love premium progressives for improved comfort and visibility. They’re also highly recommended for anyone who is a first-time progressives wearer, since they offer an easier adaptation process.

  • What are the benefits of premium progressives?
    • Fully customized, German-engineered optical lens
    • Sharper focus reduces eye strain
    • Easy adaptation between viewing areas
    • Less peripheral distortion
    • Wider intermediate and near/reading viewing areas provide maximum comfort
  • How do I order single vision distance glasses?

    Ordering single vision distance glasses through Zenni is easy! Once you have selected a frame, click “Order Glasses” and follow the below steps:

    1. First, indicate that you would like distance glasses by selecting “Single Vision” from the Prescription Type dropdown.

    FAQs: Your Guide To Prescription EyeGlasses | Zenni Optical (3)

    2. Next, you’ll need to input a Single or Dual PD (pupillary distance) under the Pupillary Distance dropdown. Check your prescription to see if your doctor measured it and wrote it down. If not, you’ll need to measure it yourself. You can learn more here.

    FAQs: Your Guide To Prescription EyeGlasses | Zenni Optical (4)

    3. The last step is to enter the distance prescription for the right eye(OD) and left eye(OS). Most glasses prescriptions are considered distance single vision unless your doctor noted it was for reading or computer.

    FAQs: Your Guide To Prescription EyeGlasses | Zenni Optical (5)

  • How do I order single vision reading glasses?

    Ordering reading glasses through Zenni is easy! Once you have selected a frame, click “Order Glasses” and follow the below steps:

    1. First, indicate that you would like reading glasses by selecting “Single vision” from the Prescription Type drop-down.

    2. Next, you’ll need to input a Near Single or Dual PD (pupillary distance) under the Pupillary Distance dropdown. For a Single PD, if you were only given one PD measurement, it is most likely for distance so you will need to subtract 3 to calculate your near single PD. If you were given a dual PD, two numbers - one for the right and left eye, you’ll need to subtract 1.5mm from each number to calculate the near dual PD. Ex. If given PD= 63mm then Near PD= 60mm.

    3. The last step is to enter the reading prescription for the right eye and left eye. If your doctor didn’t write out a separate reading prescription then you’ll need to calculate it yourself. You can do this by adding the ADD value to the SPH value and keeping the remaining values the same, as in the example below:

    Advisory for Readers

    Readers are not intended to be a substitute for corrective lenses; only a professional eye examination can determine your eye health status and vision needs.

    • Consult an eye care professional for regular eye exams.
    • Not for use as eye protection.
    • For near-vision and reading use only.
    • Not for driving or vehicle operation.
    • Not for distance vision.
    • Not for direct observation of the sun.
  • Can I order bifocals that are computer distance on top and reading on bottom?

    You bet you can! Divide the NV-ADD in half. Add one of the halves to your SPHs. Leave the other half in the NV-ADD. This creates computer vision in the top of your lens, and reading vision in the bottom!

    FAQs: Your Guide To Prescription EyeGlasses | Zenni Optical (7)

  • Can you fill prescriptions with prism corrections?

    Yes, we can fill prescriptions with prism correction in single-vision lenses only. You will enter in the values for each eye in Step 1 of the order process according to the script given by your doctor. After you fill in Sphere (SPH), Cylinder (CYL), and Axis numbers for each eye, you will click “Yes” under Prism Values. You will then select your Prism Horizontal (for Base In/Base Out) and Prism Vertical (for Base Up/Base Down) values in diopters and indicate the direction for each value on your prescription for each eye.

  • Can I use my contact lens prescription to order glasses?

    Sorry, a contact lens Rx can only be used for contact lenses.

  • How do I order non-prescription glasses?

    It's super easy to order Non-Rx glasses from Zenni Optical. After clicking on the Order glasses button, select Non-Prescription in the Prescription Type drop-down window. During the ordering process, you can turn them into sunglasses, or choose our Blokz® blue light lenses, that protect against blue light.

  • What if my prescription has expired?

    We strongly recommend that you get an eye exam every two years, or more frequently if you notice that your vision has changed.


  • What frames can be ordered as sunglasses?

    Most of the frames on our website can be ordered as sunglasses, except for some sports or goggle frames.

  • What's the difference between premium sunglasses and regular frames with tint? Do they have different lenses? Do they block the UV differently?

    Premium sunglasses are only offered in four lens index options (1.53, 1.57, 1.61 & 1.67), whereas regular frames with tinted lenses are available in 1.50, 1.53, 1.57, 1.61, and 1.67.

  • Can I order prescription sunglasses?

    Yes! With a few exceptions, the Rx glasses you order on our website can be turned into Rx sunglasses. Just select a standard or gradient lens tint, or choose from our glare-reducing polarized lens selections.

  • What is the difference between Photochromic and Polarized lenses?

    Photochromic lenses automatically darken when outdoors or exposed to UV rays. They return to clear when you are back indoors. Polarized lenses are permanent sunglasses that don't change color and are great at cutting glare.

  • Can I get sunglasses that are also thin lenses?

    Sure! If you order Rx sunglasses, you can get the lens with the index that is recommended for your Rx to keep your lenses nice, light and thin. If you get non-Rx sunglasses, your lenses will be thin.

  • What is the best tint color for sunglasses?

    We offer 3 sunglass tints: Dark Gray, Dark Amber, and Dark Green.

    We offer 8 gradient tints: Smoke Gray, Golden Amber, Dusk Blue, Sage, Desert Rose, Ultraviolet, Neon Pink and Electric Blue.

  • What are mirrored lenses?

    Mirrored lenses are created with a highly reflective coating that reduces glare by reflecting light away. These sunglass lenses are highly functional yet also fashionable.

    Zenni offers 8 different mirror colors: Silver, Gold, Rose Gold, Flame Red, Lavender, Indigo Blue, Sky Blue, and Moss Green.

  • Can I order clip-ons for any frame?

    Clip-On can be ordered for most of our eyeglasses. You can check availability by visiting https://www.zennioptical.com/clip-on-finder

  • Why are my polarized lenses distorted when I look at screens?

    If you look at LED screens through your polarized lenses, especially in bright sunlight, you might experience a ‘pinching’ effect, where certain areas of your lenses do not appear to uniformly filter light. However, this is a common phenomenon for prescription polarized lenses and not a problem with the coating application or lens quality. It should not affect the wearer’s ability to see clearly through the lens when not looking at screens. Polycarbonate is more susceptible to this effect. However, for whichever lens material you choose, this effect should gradually disappear the more you wear your glasses.

  • Do I need polarized lenses for my sunglasses?

    Polarized lenses reduce glare for improved clarity. They are ideal for people who spend lots of time driving or outdoors, especially for golfing, fishing, boating, or activities in a snowy environment.


  • Are the earring posts made with hypoallergenic metal?

    Yes, the posts are made with hypoallergenic titanium.

  • Are your acetate earrings nickel-free?

  • Can the earrings be worn in the water?

  • What do the Lens Index numbers mean?

    The Lens Index number (1.50, 1.57, 1.53, 1.59, 1.61, 1.67, or 1.74) refers to the degree of refraction the lens provides. This means how much the light that enters the lens is refracted (bent) as it passes through the lens. Lens Index is also related to the thickness of the lens. The higher the index, the thinner the lens will be. Learn more here about what index is best suited for your Rx, lifestyle, and frame selection.

  • How do I get thinner lenses?

    The lens that is preselected as a recommended option in ② Your Lenses during the ordering process will be the best option for your Rx. If you have a strong Rx, a higher lens index number will give you a thinner lens.

    Glasses fog up when you move from hot to cold environments, wear a mask or helmet, engage in outdoor activities or chores such as cooking.

    Anyone who experiences foggy lenses can benefit from adding anti-fog coating to their glasses order.

The anti-fog coating is on both sides of the lenses for most glasses and on the backside of the lenses for premium sunglasses. Each pair of anti-fog coated lenses comes with a special anti-fog activator lens cloth that activates the anti-fog properties every time you clean your lenses to help keep them extra clear.

  • What are photochromic lenses? Do you carry Transitions®?

    Photochromic lenses are specially treated to turn dark when exposed to UV light. When the lenses are out of the sunlight, they become clear again. We carry the Transitions® brand of photochromic lenses for our 1.50, 1.61, and 1.67 lenses, for both single-vision and progressive glasses.

  • What is the difference between polarized lenses and dark tints? Which one is better for what situations?

    Polarized lenses are known for cutting out glare and light intensity which is very noticeable when light reflects off of water, snow, and sand. Dark lens tints are known for only cutting down the intensity of light. Some instance where dark tints are beneficial over polarized lenses is if you are using a digital screen outdoors. This is because polarized lenses will darken your view of the screen. Polarized lenses are known to improve visibility with driving, especially in severe weather conditions, therefore making you a safer driver.

Eyewear Care

  • What can I do if my frames don't fit perfectly?

    New glasses often need minor tweaks to fit your face right. It’s best to have an optician fine-tune the glasses for you, but you can also make adjustments yourself with our How to Adjust Your Glasses guide.

  • How do I adapt to my new glasses?

    New glasses may leave you feeling a bit off-balance, so gradually increase your wear time until you fully adapt. Avoid switching back and forth between glasses, as it will take longer to adapt. It can take a few days to adapt to single-vision lenses and 2-3 weeks for progressive or bifocal lenses. If you’re still having vision issues after the adaptation period, consult your eye doctor. For more tips on how to adapt to progressive lenses visit: https://www.zennioptical.com/blog/how-to-adapt-to-progressive-lenses

  • How do I care for my Zennis?

    We're all guilty of quickly rubbing our glasses on our shirts or using paper towels to clean the lens. While these habits may seem harmless, they ultimately can end up damaging your frames.

    • Don’t use your shirt (or clothing in general) to clean your glasses. The dust and debris on fabrics can scratch your lenses.
    • Don’t use paper towels or tissues to clean your glasses. These materials are too rough for your lenses and can cause small scratches. Dish towels or other fabrics that can trap dust and debris may also scratch the lenses.
    • Avoid using household cleaning products to clean your lenses. Cleaning products usually contain harsh ammonia-based chemicals that can destroy the protective coating on your lenses.
    • Don’t leave your glasses out on the bathroom counter when getting ready. Hairspray and beauty products can get on your lenses and damage the protective coating.
    • Never try to buff out a scratch. Attempting to buff your lenses will only result in more scratches and damage. Take your glasses to a professional if you have a scratch that need to be removed.
    • Don’t leave your glasses in the car on a hot or cold day. Extreme heat or cold can damage lens coatings and also may change the frame shape.
